In addition, because you do not have to cut your OE radio plug off, the GWH-343 allows you to reinstall your factory receiver if necessary. A great example is if you sold your car, but wanted to keep your after-market radio and re-install your factory stereo receiver. We also recommend the Scosche BOBAZT for a quick connection that is sure to last.

Plugs into GM Radios 90+
Nice product, plugs right into your GM 21 Pin radio. I used this on Pontiac & GMC stereos 1997 and 1999 respectively. Works great. Wires clearly labelled.
